--noImplicitAny suggested fix on the callback parameter:

function curryThrough(callback: (arg0: string) => any) {

Actual behavior:

Related Issues: #13243 (parent tracking quick fixes)

void seems like an odd default choice for the unknown return value of a method. If the type can't be inferred from usage, shouldn't it be any?

首先使用 curryThrough 示例重现 --noImplicitAny 建议的修复，并将推断出的 callback 返回类型与预期的 any 结果进行比较。跟踪 noImplicitAny codefix 入口点和相关的跟踪 issue #13243；当该修复生成预期的 callback 类型且不会使相关 quick fixes 发生回归时，即视为完成。
